Wall-E was magnificent. It was just beautifully made and a truly touching movie. The visuals were in places truly astounding and always charming. It had an interesting story with a surprisingly serious undertone and wasn't shy about turning some emotional screws.
In short I loved it. I thought it is much better than Ratatouille. It might be my favourite Pixar movie.
Wall-E making the Mac startup sound really made the Apple fanboy in me giggle too.
